ence characters throughout( the several views. m, A hollow'handle 10v is providedwith a cap 11 on what will ordinarily'be regarded as the top side. 'Thisc'ap will normally he secured in place upon the body portion of the handle bythe screws12; f Within the handle an electric motor 13 is mounted, the operation. of this motor. being preferably.'A controlled by la switch lever 141which projects to the exterior through an opening in theside of the handle casing. ;Electriccurrent is supplied to the motor through the flexible cord 15 and a plug 16 socketed inthe 'rear end'ofthe handle. lThe front of the handle is provided with a vforwardly projecting arm 20 whichl is se- "cured to the motor supporting block 21 bya Y screw 22.` rEhe arm extendsthrough an aperture in the front wall ofthe handle'casing and i supports Va perpendicularly disposed bearing sleeve 23 in'which a s-haft124 is mounted.

fflfhe upper end of the shaft 24 is provided with a wheel having aring or pulley-like rim y25 whereby the shaft 24' may losl driven from 1 the motor shaft 26 and the motor Yshaft pulley 27 by a'belt 28 whichextends through slots 29 r'in the cap 11.v These slots extendV to the forward margin of the cap 11 and serve'- as guides for the belt, the'latterbeing released f l VvV when the cap 11`is removed. The front end of the cap`11 curves downwardly, andabelt passing through the slots may therefore "eX-f tend directly over anvinter'nal Vpulley 27 and an external pulley supported fromthe arm 20. This arrangementV allows the vmotor pulnormally' concealed` within the p ley '27 to be handle.

' V'ljhe portion of the rim 25`between itsup-V :per margin and the spokes 31 is conically ta- *90 V32. Within ,thisv portion of the rim and at-` Ypered and provided withan abrasive surface tached to the spokes 31 I preferably provide a'ring 33 which,- also hasV 'a conicallytapered j two'annular abrasive surfaces 34= and v32 *are abrasive surface .34E on its inner face. 'The Iconcentric.andare normally guarded bytheir "Y respective rims froml coming into` contact with the skin or withany surface upon which s thetool may be placed. v l-loweverthe finger ,Y .Y 1 v `nails or toe nails'of theperson beingmani-:10U f cured can be so placed as to bring them in Contact with either of these abrading surfaces without danger Vof material injury to the person since contact with any such surface will cease the moment that effort to maintain such Contact ceases.

In addition to the protection afforded by the rim guarding the abrading'surfaces 32 and 34 it will be found that the internal or concave curve of the are within which the finger nail is placed will-conform quite closely to the curvature of the linger nail whether applied to the end thereof or to that portion of the outer surface of the finger nail which can be brought into contact with the abrasive. Therefore a smooth continuously curving surface or edge without hollows or ridges may be more easily obtained than would be possible to obtain by means of a convex abrading surface such as is provided where the abrasive is applied to the outer surface of a wheel rim.

At the opposite end of the shaft 24 from that to which the abrading wheel is applied the shaft is provided with a polygonal end portion 38. This portion of the shaft is preferably hexagonal and when the end of the shaft is applied to a finger nail adjacent to its inner end or root the corners 39 will successively" impact upon the skin margin to push the latter backwardly while the end of the shaft is buffing the nail. This impacting pressure is very effective to prevent the skin from encrouching upon the surface of the nail and to massage it into healthy condition, removing all dead cuticle.

I preferably employ a belt 28 composed of a flat rubber band which combines al high frictional characteristic with a high degree of elasticity. Such a belt will drive the pulley under exceedingly light tension because of its frictional engagement with the pulley surfaces.. And yet its high degree of elasticity allows it to stretchand instantly release the pulley without overloading the motor or causing the pulley to injure the finger when the latter is carelessly inserted between the spokes `or pressed with excess-ive force against the abrading surface.

In `5 I have illustrated a modification in which a conically tapered ring 40 is provided with internal and external abrading surfaces 41 and 42' respectively. This rim is supported by spokes 43 from 'a hub 44 attached to a supporting shaft 45. This shaft V`may be driven from any suitable source of power, but inthe construction shown it is driven from a flexible shaft 46 through the pinion carrying shaft 47 and beveled pinions 48 and 49, the latter being secured to shaft 45. The flexible shaft has -a splined end portion 50 telescoped in the associated end of shaft 47 -and held in position by a cap 5l screwed to theend of the gear casing 52. The gear casing is elbowed and receives the .gears in the elbowed portion, the shaft 45 passing through a detachable cap 54. In this Fig. 5 construction it is not material to the invention herein disclosed whether the outer surface of the rim 4() is provided with abrasive, and it will be obvious that if abrasive is used on the outer surface of this rim there will be greater danger of injury to the person or thing than will exist if the exterior abrasive is omitted.

I claim:

- l. In a manicuring tool a driven pulley rim having power transmitting connections andv provided with an internal abrasive surfacek adapted for operation upon the outer 'end portions of finger nails, said rim being surface adapted for operation upon the outer end portion of linger nails, said surface being conicallytapered from the outer margin of the rim toward a-central plane.
